Part Number: TPA3221 Other Parts Discussed in Thread: LM317 , TPA3220 Hi Guys, Made this TPA3221 PCB with EVM suggested components but hrere is the problem.
Part Number: TPA3221 Hi,
I am designing a 4 channel amplifier board with TPA3221.
All four channels shall have 30dB gain.
I don't feel 100% sure that I have made the correct connections when synchronizing the two IC's. Please help me to review the…
Part Number: TPA3221 Other Parts Discussed in Thread: TPA3223 , TPA3251 Tool/software: Hi
Customer designed a 2 * 200W (2 Ω load) digital amplifier board, using TI's TPA3221 chip and PBTL mode. This is a PCB picture of the amplifier board and power…
Part Number: TPA3221 Hi Expert,
Customer is using TPA3221 but found high failure rate after 10-20mins of aging test.
Failure units shows low impedance or infinite value for pin 5,6,7,35, 39, 40 per customer's quick multi-meter measurement. Could you…
Part Number: TPA3221 Hi Team,
Design requirement:
when TPA3221 over load, the output is shut down. the FAULT pin trigger the TPS3808G MR pin, causing TPA3221 to RESET and regain output.
currently problem:
after TPA3221 RESET, the FAULT pin returns…
Part Number: TPA3221 Hi TI Expert,
We might need to adjust the GAIN setting during the testing.
Adjusting the resistance on the GAIN pin might not works.
For example, using IO signal to control the MOSFET ON/OFF status to change the voltage level…
Part Number: TPA3221 Tool/software: Hi expert,
The customer's ButtKicker home amplifier products have chosen TPA3221. What is the AMP Standby mode setting? The datasheet describes the availability of Standby mode, how to enter Standby mode.
Best regards…
Part Number: TPA3221 Tool/software: Good day TI experts,
Asking advices about the Mute function on TPA3221. I'm working to add external switch to mute pin. What I want is when the switch is open the device is muted, and when the switch is closed, the…
